Tin containing products

Pure metals

Pure metals, such as tin, are substances under REACH and require full substance registration. Further information on the REACH status of some of the non-ferrous metals can be found here.

Alloys

Under REACH an alloy is defined as ‘a metallic material, homogenous on the macroscopic scale, consisting of two or more elements so combined that they cannot be readily separated by mechanical means.’ In most instances alloys are considered to be preparations, albeit special ones, as it has been recognised that they have properties that are distinctive from those of their constituent metals. Further information on the pre-registration and registration requirements for imported alloys can be found here.

Ores and Concentrates

Minerals, ores, and ore concentrates are exempt from registration unless they have been chemically modified. They are also exempted from the downstream user and evaluation obligations of REACH. Further information on ores, ore concentrates and REACH can be found here.

Tin Chemicals
Manufacturers and importers of inorganic tin chemicals (in quantities of 1 tonne or more each year) are responsible for registering dossiers of information about those chemicals with the European Chemicals Agency. In order to relieve some of the burden, companies are being encouraged to work together and share the costs.

Inorganic tin chemicals groupings
In REACH, there is a general obligation to use any available test data on the substances themselves. However, if no test data are available, the process of “read-across” may be used. To this end, the Chemicals Agency on-line registration system will require a registrant to point out other similar compounds to the one being registered which should be considered for read-across. This aims at minimising further testing of compounds which are currently lacking the eco-toxicological and toxicological information which will be required for substance registration under REACH.

Organotin groupings

Manufactures of stabilizes and catalysts based on organo tin (IV) compounds have formed the Organotin Consortium. More information can be found here
